Cosmos bipinnatus Dazzler may well be the best of the dark pink flowered Cosmos being a gorgeous rich carmine. Newly opened, it is nearly blood red. Certainly beautiful enough to get it into our collection of ready to plant cosmos seedlings.
We wax lyrical with all the Cosmos because they are the most astonishingly floriferous subjects. One of the experiments we carried out when we were trialling our range was to plant a drift of 15 Cosmos Dazzler and then cut as many as we could every Friday (none were wasted and staff took them home!). We always filled one Vileda bucket (which are quite large) and if the sun had been shining, we usually filled a second. That went on from late May until the end of October. Simply staggering quantities of flowers.
Dazzler is a lovely colour and so also works very well in containers - it sets greys and silver off very well, so try it in one of those galvanised, zincy things that seem to be all the rage at present. Add a bit of lavender, maybe some Cosmos Purity and you are away.
As with all Cosmos, you have to keep cutting to keep the flowers coming and a bit of liquid tomato fertiliser works wonders for flower quality as the summer wears on.
